The high Jolly 14 day limit BLM dispersed camping area is a couple of miles south of Plumosa Road. Plumosa Road is the northern most BLM area and is also a 14 night limit. South of Quartzsite are 6 more areas. South of Quartzsite are for long-term visitor areas (LTVA). You can stay there for the whole season for $180 including dumpsters pit toilet water. The LTVAs are  Laposa West, Laposa North, Laposa south and the Tyson wash BLM area. South of that is the 14 day limited area called road runner wash BLM. West of town is the dome rock 14 day area and to the east is Scadden wash, another 14 day area. The signs say you must register your vehicles with the camp host by filling out a form for free where they will write in the date of your arrival and the day you must leave. However a lot of people do not do that and I've never seen any authorities come around and tell people they have to move the minimum 25 miles.
